动态大地测量的平差基准
Adjustment Datum for Dynamic Geodesy
-
摘要: 从平差基准的基本概念出发,说明动态大地测量的平差基准的意义和基准的数量,讨论动态高程系统的转换关系,建立等价于原观测值的坐标差与速率差的观测方程及基准方程,并通过分析说明,四维大地测量平差必须恰当地选取平差基准,才能得到具有参考价值的结果。Abstract: The datum transformation relationship between the dynamic height network and dynamic plane control network is introduced in this paper.And in turn,the dynamic space network,i,e.the transformation relationship for 4-dimension geodetic datum,is also discussed.
